These lights may be of any character Fig. 3 is a horizontal section through a por-- desired, and I propose to provide for each opention of one sash and its adjacent wall structure, ing two kinds of lights, a window pane 15 and a taken on the line 3-3 of Fig. 1; screen element 16. The Window pane is conven- Fig. 4 is an end elevational view, partially iently a frameless plate of glass, and the screen 55 broken away, of a sash; element 16 may be an area of wire mesh bounded by a metal margin binding. Both lights are of equal size and are readily interchangeable. A storage compartment 17 may be mounted on the wall 1 below the window to contain the extra lights of the window when not in use, as shown in Figs. 1 and 2.

In order to retain the lights in position in the sash, to assist in pre enting rattling thereof, and to provide a jamb or abutment for the free or lock stile of the sash and the surface against which it closes, I provide an astragal 18. This element comprises a channel member, preferably of metal, having a center web 19 and two unidirectional edge flanges 20, 20. To one of the flanges 20 is secured a jamb element 21 of approximately twice the width of the flange, flush therewith at the free edge of the flange, with the remainder of the element 21 extending beyond the plane of the web 19 to provide, when the astragal is mounted on the stile, a pocket to receive the corner of the element against which the sash closes.

The astragal may be secured to its stilein any convenient way. Figs. 5 and 6 show a preferred means for connecting these two parts of my structure, comprising a tongue 22 conveniently I made integral with the web 19 of the astragal,

which serves as a hook for and cooperates with a cleat 23 positioned across the edge of a stile which is recessed at 24 behind the cleat to accommodate the tongue 22. The cleats are provided preferably in the edge of the stile along the line of each rail of the sash, and the hooks 22 are formed on the astragal in an equal number and positioned to engage the cleats when the astragal is in place. The astragal may thus be hung on the stile in an obvious manner.

Fig. 8 shows an astragal in place on each of the cooperating free edges of the two sashes of a casement window from which illustration the manner in which each astragal, or pair of astragals, functions to support and seal the edge of the sash will be apparent.

I prefer to make the width of each interchangeable light somewhat less than the width of the opening in the sash which receives-it. Consequently the outer edge of each light is inset from the lips of the slot 14. To facilitate withdrawal of a light I employ a grip 25 pivoted to the free edge of each light and having a spring element 26 secured to its end portion and bearing against the edge of the light, as best shown in Fig. 6. The dimensions of the grip are such that when the astragal is in place on the sash the grip is held entirely within the slot 14. The spring 26 exerting tension between the astragal and the free edge of the light, assists in preventing rattling of the glass or screen margins. When the astragal is removed the spring moves the end of the grip outwardly beyond the lips of the slot 14, where it can be grasped to pull the light from the opening.

A friction bolt 27 may be set in the upper rail 10, lower rail 11, or both, to enter the adjacent sills of the frame and frictionally maintain the sashes in their closed position.

I prefer to employ means to seal or weatherproof each sash in the form of a packing ele ment 28 contained within an indentation in the outer edge of the bead 4 and extending therefrom sufiiciently to engage a portion of the surface of the hanging stile 8 when the sash is closed. This sealing agent is especially desirable when the sash contemplated by the present invention is associated as a storm sash with a conventional pair of sliding windows, as shown in Fig. 3.

It will be understood that the invention has been described and shown in a preferred form of embodiment only, merely for exemplification of the details thereof. It is to be understood that the invention is capable of embodiment in other and further modified forms, and all such modifications to the extent that they embody the principles of the invention as pointed out in the appended claims are to be deemed within the scope and purview thereof.

I claim:

1. A sash construction including a pair of cooperating casement sashes each having a stile provided with a slot opening therethrough to admit a removable light, in combination with an astragal detachably connected to each of said stiles having a portion overlying and closing the slot therein and having a right angularly dis-- posed jamb portion adapted to overlie a portion of one face of the corresponding stile of the cooperating sash.

2. A sash construction including a hanging stile and a lock stile, the lock stile being provided with a slot opening therethrough to admit a removable light, and an astragal detachably connected to the lock stile having a portion overlying and closing the slot therein and having another portion right angularly disposed to the first portion adapted to constitute a jamb for the lock stile of a cooperating sash.

3. A sash construction including a stile provided with a slot opening therethrough, a removable light for the sash adapted to be admitted and removed through the slot, a grip connected to the light adapted to be grasped in manipulating the light, and an astragal removably connected to the stile to cover and conceal the slot and the grip.

4. A sash construction as claimed in claim 3, in which the grip is pivoted to the light ;and includes spring means for projecting a portion of the grip through the slot beyond the edge of the stile when the astragal is removed.

5. A sash construction as claimed in claim 3, in which the grip is pivoted to the light and includes spring means normally urging the grip against the astragal and adapted to project a portion of the grip through the slot when the astragal is removed.

6. A sash construction including a stile having a slot opening therethrough to admit a removable light, an eye provided on the outer edge of the stile which is normal to the plane of 130 the light, and an astragal having a hook engageable with the eye for detachably connecting the astragal to the stile to cover and conceal the slot.

'7. A sash construction as claimed in claim 6, in which the sash includes an upper rail and a lower rail, an eye is provided on the stile edge in the line of and opposite each of said rails, and a plurality of hooks are carried by the astragal, each of said hooks engaging one of said eyes.

8. A sash construction for a wall having a window opening including a member framing the opening provided with an outer and an inner step, and a casement sash having a stile hinged to the outer step of the member and adapted to close against the inner step, the inner step being recessed and provided with a packing body adapted to engage the sash stile in sealing contact. 150

9. A sash construction for a wall having a window opening including a sliding window mounted in the opening, a window bead confining the sliding window in the opening having an indented outer surface, a member secured to the wall at the margin of the opening, a-packing element contained in the indented outersurface of the bead, and a casement sash having a stile hinged to the member and adapted to contact with the packing element in sealing engagement.

10. An astragal for a hinged sash comprising a channel member adapted to embrace the free edge of the sash and a jamb portion fixed to one flange of the channel member.
